A pump delivers water from one reservoir to another reservoir at through 120 m of 0.05-m-diameter pipe. See the figure below for several pipe–fittings installed on the pipe-line. The surface of the pipe is rough . Calculate the power of the pump required for the water–transfer.
(Fig. 24a)
Before writing energy balance equation, one should make a note that there are several minor losses between (1) and (2) and a major loss due to friction in the pipe. Let us list such minor losses:
from one reservoir to another reservoir at 
through 120 m of 0.05-m-diameter pipe. See the figure below for several pipe–fittings installed on the pipe-line. The surface of the pipe is rough 
. Calculate the power of the pump required for the water–transfer.
